conductive polymer

While PEDOT:PSS is the most widely used conductive polymer commercially, it is derived from petroleum. The sulfonic groups in PSS interact with the cations on PEDOT. Therefore, we hypothesized that by using sulfonated lignin, a biomass-derived material, as a dispersion stabilizer and dopant instead of PSS, we could create conductive materials with a lower environmental impact. In this study, we devised a synthesis method that utilizes the unique properties of lignin and investigated its characteristics.
